The most dangerous use of a serial number on a firearm is as a registration number. In effect, gun registration is gun confiscation. It was not the intent for which serial numbers were made. They were originally created as a way to track firearms with production changes and as a way for government arsenals to track production and military use of weapons.
A federal court recently held a federal law, passed in 1990, which makes possession of firearm with a removed serial (registration) number illegal, is unconstitutional.
This is an important decision. It has relatively minor effects, at this time. The law was a step toward universal firearms registration.
Finding the law unconstitutional subverts the push for government control over firearms.
If a person cannot be punished for the mere possession of a firearm from which a serial number has been removed, the entire scheme for government control over legally owned firearms falls apart.
There cannot be effective gun registration, if a person cannot be punished for possessing a gun which has had the serial number removed.
The legal ability to possess firearms without serial numbers buttresses the deterrent effect of an armed population. .....
